- Multi-stage Dockerfile: discover patterns from PMS binary (capstone), compile .so with zig (musl), layer onto lscr.io/linuxserver/plex - Uses LD_PRELOAD instead of patchelf (which corrupts Plex's musl loader) - Auto-discovery: broad structural patterns with string-anchored fallback (//feature) and relationship-based fallback (BITSET_REF within BS_INIT) - hook.cpp uses __has_include for generated patterns with hardcoded fallbacks - Custom wrapper.sh (no traffic_logger preload) - Vendored Freeloader source (github.com/authrequest/Freeloader, AGPL-3.0) - Removed stale plexmediaserver_crack.so binary - Supports Plex 1.43.3+ (verified against 1.43.2 and 1.43.3)
